Isntree C-Niacin Toning Ampoule
Description
The C-Niacin Toning Ampoule by Isntree is a vitamin-rich radiance ampoule with 69% sea buckthorn fruit extract. It restores luminosity to dull, tired complexions and helps even out skin tone.
Its fluid texture can be applied all over the face or as a targeted treatment. Sea buckthorn (Hippophae rhamnoides), naturally rich in vitamins, and niacinamide revive radiance and reduce the look of irregularities, while a hydrating complex based on aloe vera, sodium hyaluronate and beta-glucan strengthens the barrier for a more translucent complexion. 50 ml bottle, to pair with the C-Niacin Toning Cream.
